ON THE STRUCTURE OF BUDS 127 



become petiolate owing to their being much wider 

 than their insertion. They are glabrous, as long as the 

 bud, rolled round three-fourths of it, the outer one 

 covering the same extent as the inner, which is more 

 membranous, except at the tip. They are accompanied 

 by a small, conduplicate, silky leaf. 



The next pair are broadly elliptic, unequal, mem- 

 branous, and more or less silky on both surfaces. The 

 larger scale or stipule is always the outer of the pair. 

 The second leaf is much larger than the first, densely 

 silky, with unequal parts, the narrower one being 

 uppermost. The edges of the leaf are always directed 

 under the larger stipule ; and it will be noted that 

 the direction of the leaf and the larger of each pair 

 of stipules are altered in each succeeding set. This 

 is due to the alternate and distichous arrangement 

 of the leaves. 



The fourth pair are oblong-elliptic, covering three- 

 fourths of the bud, as in succeeding cases, and more 

 silky than the previous pair on the outer face, but 

 otherwise similar. The leaf is as long as the next 

 younger pair of stipules, and lies in a convex manner 

 over them. 



The fifth pair are oblong, and the outer stipule 

 covers less tlian half of its fellow. The sixth pair are 

 more unequal and very much smaller. The seventh 

 pair are oblong-lanceolate and very small ; while the 

 eighth pair are still smaller and membranous.
